- 1Use the estimated |V|(0) and δ(0) to calculate the injected active power Pcalc(0) and the active power mismatch ΔP(0) for all buses except the slack bus.
- 2Use the estimated |V|(0) and δ(0) to calculate a total of n injected reactive power values Qcalc(0) and equal number of reactive power mismatches ΔQ(0) across all buses including the slack bus.✓
- 3Choose initial values of the voltage magnitude |V|(0) for all PQ load buses and angles δ(0) for all buses except the slack bus.
- 4Use the estimated voltage magnitudes |V|(0) and angles δ(0) to formulate the Jacobian matrix J(0).
Correct answer
Use the estimated |V|(0) and δ(0) to calculate a total of n injected reactive power values Qcalc(0) and equal number of reactive power mismatches ΔQ(0) across all buses including the slack bus.
